To sort the information shown in the tables by a particular indicator, click the 
column label by which you want to order things. For example, if you want to see 
the table rows ordered by signal strength, click the Signal column label. The 
entries are sorted by signal strength.

When Channel Management is enabled, the access point automatically assigns 
radio channels used by clustered access points. The automatic channel 
assignment reduces mutual interference (or interference with other access points 
outside of its cluster) and maximizes Wi-Fi bandwidth to help maintain the 
efficiency of communication over the wireless network.

You must start channel management to get automatic channel assignments; it is 
disabled by default on a new access point.

At a specified interval, the Channel Manager maps access point

s

 to channel use 

and measures interference levels in the cluster. If significant channel interference is 
detected, the Channel Manager automatically re-assigns some or all of the access 
point

s

 to new channels per an efficiency algorithm (or 

plan).

Strength of the radio frequency (RF) signal the client 
receives from the access point.

The measure used for this is a value known as 
Received Signal Strength Indication 
(RSSI), and will be a value between 0 and 100.

RSSI is determined by a mechanism implemented on 
the network interface card (NIC) of the client station.

Number of total packets received by the client during 
the current session.

Number of total packets transmitted to the client 
during this session.

Percentage of time frames are dropped during 
transmission on this access point.
